First record of Leucorrhinia caudalis for Bosnia and Herzegovina ( Odonata : Libellulidae )
On 30-iv-2013, a single young male of Leucorrhinia caudalis (Charpentier, 1840) was collected at a gravel pond near Banja Luka, Bosnia and Herzegovina. This is the first record of the species for the country and its southernmost occurrence in southeastern Europe, where it is an extremely rare species, restricted to the floodplains of the Sava and Danube Rivers. Recent surveys suggest further decline of the species in the region. Habitat characteristics at the capture site correspond with the previously described preferred habitats of the species. Floating and submerged vegetation was well developed and dominated by Pota mogeton spp. and Myriophyllum spp., while sedges and reeds grew along the margins. The distribution, habitats and status of the species in the Balkans and central Europe are outlined and discussed (western Balkans, Hungary and Slovakia). Data on the species’ distribution in western Europe are also provided.
